Anterior and Medial Thigh Flashcards
Tributaries to great saphenous Vein
External Pudendal Vein
Superficial circumflex iliac vein
superficial epigastric vein
Superficial inguinal nodes and their groups
drain all superficial structures in lower extremity except dorsolateral foot and posterior calf (popliteal lymph nodes)
Horizontal group: superior
does anterior abdominal wall, penis, vagina, anal canal, lateral thigh
Vertical group: inferior
Cutaneous Innervation: lateral femoral cutaneous N
L2-L3
sensory andterior and lateral thigh
Cutaneous Innervation: femoral branch of genitofemoral N
L1-L2
sensory: scrotum/labia majora/medial thigh
motor: cremaster muscle
Cutaneous Innervation: Obturator Nerve
L2-L4
sensory: medial thigh
motor: obturator externus, adductor longus, adductor brevis, gracilis, upper fibers of adductor magnus muscles
Cutaneous Innervation nerves of the thigh
intermediate femoral cutaneous N
medial femoral cutaneous N
ilioinguinal N
Meralgia paresthetica
gun belt palsy
impingement of the lateral femoral cutaneous nerve
tingling numbness of the lateral thigh
heavy belts cause this
Iliotibial Tract
fibers of the fascia lata of vertical orientation
aponeurosis of gluteus maximus and tensor fascia lata
inserts into gerdys tubercle
-anterolateral tubercle of the tibia
Psoas Major Muscle
transverse processes to lesser trochanter of the femur
laterally flex the vertebral column and flexes the trunk and the thigh when working with iliacus m
Anterior Rami Lumbar plexus L1-3
Iliacus M
superior iliac fossa to lesser trochanter of femur
flex the thigh and stabilize the hip
Femoral N
Medial Femoral circumflex a and the iliolumbar a
Sartorius M
longest muscle of the body
anterior superior iliac spine to the medial aspect of the tibia
flex, abduct, and laterally rotate thigh, and flex leg at knee
femoral N
rectus femoris M
anterior iliac spine and ilium above acetabulum to base of patella crosses 2 joints

Femoral N
Vastus lateralis M
greater trochanter to lateral patella
extend knee
femoral N
Vastus Intermedius M
Anterior and lateral serfuce of femur to base of patella
extend the knee
Femoral N
Vastus Medialis M
interochateric line to medial aspect of patella
Extend the knee
Femoral N
Articularis Genu M
anterior surface of distal femur to articular capsule of the knee
tightens capsule of knee during knee extension
Femoral N
Femoral N cutaneous distribution
supplies the anterior thigh and part of the medial thigh
transitions into saphenous n
runs with the great saphenous v and supplies the medial aspect of the leg and ankle
Anterior compartment of the thigh muscles
iliacus M
quadraceps Femoris M
sartorus m
pectineus m
Acetabular branch of obturator A
provides blood supply to ligament of the head of the femur
can originate from the medial femoral circumflex a
Medial compartment of thigh muscles
Adductor longus M Adductor brevis M adductor magnus M gracilis M obturator Externus M
pectineus M
superior pubic ramus to pectineal line of the femur
adduct and flex the thigh
Femoral N
obturator A
Adductor longus M
Body of pubis to middle 1/3 of the linea aspera
Adduct the thigh
anterior division of Obturator N
Deep femoral A
Adductor Brevis M
body and inferior pubic ramus to pectineal line
Adduct thigh and assist in flexion
Anterior division of obturator N
Deep Femoral A
Adductor Magnus M
ischiopubic ramus and ischial tuberosity to hluteal tuberosity and adductor tubercle
whole muscle: adduct the thigh
upper fibers: flex thigh
lower fibers: extend thigh
upper fibers: posterior division obturator N

Deep femoral A
Gracilis M
inferior pubic ramus to medial aspect of proximal end of tibia
adduct the thigh and assist in medial thigh rotation and flexes the leg
Anterior division of obturator N
Obturator Externus M
external surface of the obturator membrane surronding margins of obturator foramen goes to posterior to neck of femur and attach on the trochanteric fossa
lateral rotation of thigh and helps hold femur in acetabulum
anterior division of obturator N
Obturator A
Hunters canal
narrow conical tunnel located in thigh between: vastus medialis m laterally
sartorius m anteromedially and adductor longus m abd adductor magnus m posteriorly
contains the femoral vein and artery and saphenous nerve and nerve to vastus medialis
runs from the apex of the femoral triangle to the adductor hiatus
What exits adductor canal
Popliteal A and V
Groin Pull
Strain/streching of proximal attachments of anteromedial thigh muscles
proximal attachment are in inguinal region at the junction of the thigh and trunk
